CASH'. REGISTER.

Application filed July 28, 1924. Serial No. 728,691.

This invention relates to cash registers and is shown carried out in connection with a machine of the type shown inthe E. J. Von Pein application, Serial No. 460,882, filed April 13, 1921.

An object of this invention is to provide controlling means which compels the issuing of two receipts for every registration.`

Vith this `and incidental objects in view, the invention consists of certain novel features of construction and combinations of parts, the essential elements ofwhich are set forth in appended claims and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of this specification.

The invention is carried outin connection with machine of the general ytype shown in Letters Patents of the United States to Carney, No. 497 ,860 and No. 683,877, granted May 1893 and October 1, 1901, respectively, andis an improvement applied to the machine shown in the E. J. Von Pein application, Serial No. 460,882, filed April 13, 1921.

Described in general terms, themachine comprises a series of manipulative devices an arm 33 pivoted on a stud 34, to swing forward and under the rear edge 35 of the key coupler, `in which position the key coupler is retained until after the printing operation has been completed. The key cou pler is provided with trunnions 36 having bearings in side frames 3'? and 44. Attached to the rear end of each key is an upright member 38 formed with a shoulder 39 adapted, when the key 3() is operated, to engage a transverse rod 4() of a rockingframe 41 pivoted on a transverse rod 42, to rock said frame a distance corresponding to the value of the operated key. There is a frame 41 for each denominational group of keys 30. Each frame has attached to it a registering segment 43.

A main driving shaft 50 is given a revolution 'in a counter-clockwise direction each time a hey is operated. A 'stud 51 projecting from the right end of the key coupler 32 carries a roller 52 which operates within an opening 53 in a rack plate 54 provided with `two groups of rack teeth 55 which alternately mesh with a gear 56 fast to the shaft 50. As the plate 54 is moved upward by depressing a 1Key, the rack 55, which is normally in engagement with the gear 56, will cause the shaft 50 .to revolve 1800 in a countercloclrwise direction. An ear 57 formed on the plate cooperates with a lug 58 projecting from the side frame to retain ysaid rack in engagement with the gear 56.

Near the end of the upward travel of the plate 54 its end 59 enga-ges an angle face 60 of a spring-clrawn arm 61, thereby putting this spring` under tension. klll/Then the ear 57 passes above the lag 58 the spring arm will canse the plate 54 to swing to the right,

`thereby disengaging the rack, normally in mesh with the gear 56, from said gear and moving the opposite rack into mesh therewith, and, as the key coupler 32 returns to its normal position, the plate will travel downward with the ear 57 to the right of the lug the ear passes beneath the lug 55, a spring 02. attac red to the lower end oi the plate 5l, will return the plate to its normal position, as shown in Fig. 1. The downward travel otl the plate completes the cycle ot the strait 50.

The totalif/.cand indicators, which are o'f the usual form, are not shown here but are fully illustrated and described in the patents and application previously referred to.

Printer.

(lilly so much otl the printing mechanism is shown as is necessary to properly set forth the invention.

ihe registeringsegment lli (Fig. 1) is in inesh with a pinion secured. to the leilt hand end of a telescopic sleeve 71 which extends through the right hand side iframe est oil' the machine into the printing mechanism, where it has secured to its right hand end a printing wheel 72 (Fig. 2). rlhere is a printing wheel for each denominational group of registering keys which print the detail transactions on a record strip and also upon the two receipts issuing strips which will hereinafter be described.

The printing mechanism is operated by a manually operated crank 7 3 (Fig. 2) which is rotated in a clockwise direction to drive a cam shaft 7 t in a counter-clockwise direction. The operating crank is freely mounted on a stud 75 supported in a printer 'frame 7 6 and is secured to a sleeve lwhich has mounted on its inner, or lett hand, end a pinion 777 which meshes with a gear 78 securely mounted on the cam shaft 7&1. The shaft 74 and gear 78 are of such proportion that it requires two revolutions of the crank 7 3 to cause one revolution of the cam shaft Formed in the side of the gear 7S is a cam race 79 which engages a roller 80 carried on a stud mounted in an arm 81 pivoted on a pin 82 which is supported in the printer trame 7 0. The left hand, or forward, end of the arm 81 carries a stud 88 engaging an elongated opening Sil Jformed in an impression platen bearing member 85, which has a downwardly projecting arm 8G biturcated to straddle the operating crank sleeve to guide the platen beariin;r member in its vertical movement.

The cam race 79 is formed so as to raise and lower the platen bearing member 85 during each operation of the machine to malte the proper legible impressions upon the issuing receipt 87, as shown in 7.

The platen bearing member S5 (Fig. 2) supports four platens 02 which cooperate `with the printing wheels "2. an electroplate 93, date and consecutive number printing wheels 94; and an electroplate to print the two receipts shown in Fig. 7.

The receipts are printed and severed from a strip 96 which is unwound from a supply roll (not shown) and passes under guide stucs 97 and 98, between an inliing` ribbon 0S) andthe impression platens, and between two 'l-'eed rollers 100 and 101 past a severing plate 100.

The iced rollers are olf standard ilorin 'for .this type ot machine. rlhe lower roller 100,

which is the driving roller, is operated by a pawl and ratchet mecliauisn'i, not shown here but lfully described in the application previously referred to. The pawl is n'iounted on an arm secured to a shait 103 (Fig. 3) which is oscillated by a pinion 101 pinned to the sna'it and meshing;l with a segment arm 105 freely mounted on a stud .10ol supported in the trame ol;l the machine. The segment arm is oscillated during cach operation oit the machine by a pair of cams 107 and 108 secured to the shaft 7 et and engaging rollers 109 and 110, respectively., which are carried on studs mounted in the segment arm.

The tension roller 101 is n'iounted on a spring' tensioned arm 115 pivoted at a point 116 and provided with a laterally projecting pin 117 engaging a manually operated .lever 11S to enable the operator to dis-'engage the tension roller Vfrom the 'leed roller when starting a new supply oi receipt paper.

rlhe inlringA ribbon 00, being ot the usual endless belt type, is given a slight movement during each operation ot the machine by a roller 119, the driving` mechanism Vlfor which is not shown here but is Yfully illustrated and described in the application previously referred to. rlhe ribbon is held taut by a tension roller 120.

To maize it possible to issue two rec Aipts during one operation oi the machine it is necessary to have a controllingl meclninif-an which will compel two operations oi'- the printing mechanism and 'four cycles of the operating crank 73 to one operation oi" an item key 30.

Depression of an item liey which raises the key coupler (Fig. 1) and allows the arm to swing 'forward under said lev coupler and retain it in its raised positioh. and the key in its depressed position, rotates the shaft 50 through an angle oi"l 180. Pinned to the rigl'it hand end oit the shaft 30 a dish 119 (Fig. 3) having a cam race 120 engaging a roller 121 carried on an arm lreely mounted on a stud 1253. As the disl; 119 moves in a counter-clockwise direction it will cause the arm to swing` on its pivot to the extent of elevating its projection 19.1 above a roller 125 carried by a bell crank lever 126. ."his bell crank lever is under the tension of a spring 127 which causes the lever to move clock vise when the projection 12a*- is raised above the roller 125 The clockwise movement ot the lever 126 will disengage its right hand end 128 from a square pin 129 mounted on a disl; 130 fastened to the cam shaft 74.

Freely mounted on the stud 123 and fastened to the arm 122 by a stud 131 is a three-armed lever 132 which moves in unison with arm 122. Carried on af stud mounted in the left hand arm 133 of this lever is a roller 134 normally engaging the lower one of tivo notches 135 formed in a spring-pulled arm 136 freely mounted on a stud 137. As the lever 132 is moved clock- Wise by the cam 120, the roller 134 moves from the lower to the upper notch 135, Where it retains the lever in its operated position until the lever is ret-urned to its normal, or home, position after the tivo receipts have been printed.

A right hand arm 139 of the lever 132 normally engages a plate 140 pinned to the cam 107. l/Vhen the arm 122 moves clockwise both arms 128 and 139 Will disengage from their respective stopy members 129 and 140 and permit the shaft 74 to be rotated by the operating crank 73 (Fig. 2).

The lever 126 (Fig. 3) is pinned to a rod supported .in the frame of the machine. An arm 146 (Fig. 1) also pinned to this rod carries a pin 147 Which engages a bifurcated projection 148 on the arm 33 to rock the arm counter-clockwise under the lrey coupler at the time the key 30 is depressed. The reason for having the tivo arms 128 and 139 engaging separate members to normally prevent rotation of the shaft 74 is that the arm 128 is provided to lock the shaft until the arm 33 (Fig. 1) is under the key coupler. The arm 139 locks the shaft 74 until the shaft 50 has received its initial movement. )Vere it not for the arm 128 it Would be possible, by manipulation of the parts associated with they arm 33, to operate the printing mechanism vvithout retaining a key 30 in depressed position.

The number of cycles of operation of the cam shaft 74 (Figs. 3 and 4) is controlled by a cam 149 secured to the shaft 74 cooperating With a rotatable plate 150 freely mounted on a stud 151 supported in the lever 132. The plate 150 has four arms, one of which will engage the cam 149 during the second cycle of operationA of the cam shaft 74. The plate is retained in its various radial positions by a spring-tensioned pawl 152 engaging a ratchet Wheel 153 Which is secured to the plate.

The plate 150 is rotated in a counterclockwise direction by a spring-tensioned paivl 154 pivoted at 155 to an. arm 156 which is freely mounted on the stud 151. This arm carries a roller 157 engaging an elongated opening 158 formed in the segment arm 105. As the segment arm moves counter-clockwise, as previously described, theY arm` 156 will be moved in a like direction and rotate the plate 150 a space equal to one division of the ratchet Wheel 153.

Referring to Figs. 3 and 4 the parts'are shown in their home positions. As the disk 119 is rotated 180O by the downward movement of an item lrey 30, the plate 150 will be placed in a cooperating position with the cam 149, but as the segment arm 105 is moved in a counter-clockwise direction before the cam 149 reaches a position to engage the plate .150, this plate will have been rotated one division of movement placing it in a relation to the cam 149 as shown in Fig. 5, in Which position the cam will rotate Without engaging the plate, thereby allowing the shaft 74 to continue rotating for a second cycle of operation. Bering the second cycle of operation the segment arm 105 will operate as during the first cycle and Will again cause the arm 156 to rotater the plate 150. one division of movement Which will place the plate in a relation to the cam 149 as shown in 6, in Which position the cam will engage an arm of said plate and cause the lever 132 to move on its pivot in a counter-clockwise direction, moving the roller 121 in the radial slot of the disk 119 toward the shaft 50, and raising the arm 139 into position to engage the stop member 140 and stop the loperatioi'i of the machine after the second cycle of operation.

As the roller`121 is moved toward the shaft 50 it enters the circular slot 120 of the disk, permitting the shaft- 50 to complete. its

rotation and return the depressed item key and its associate parts to their home pesition.

In the modified form shoivn in Figs. 8, 9 and 10, the mechanism issubstantially the same as that shown in the first embodiment.

rlhe shaft 50is given a rotation of 180O by depressing an item key, which causes the cam 120 to move thc arm 122 into the position shown in Fig. 9, Where it is retained by a spring-tensioned arm 164 pivoted at 37 and having a shoulder 165 engaging a flat sided pin 166 fastened in an arm 167 of a three-armed lever 168 freely mounted on the stud 123 and secured to the arm 122 by a stud 131.

Pivotally mounted on a stud 169 carried by the lever is a spring-tensioned bell crank arm 170 which is engaged by a cam 171 at cach revolution of the cam shaft 74 to which said cam is secured.

luring the first cycle of the shaft 74`the cam 171 will engage the arm 170 and cause it to swing on its pivot 169 in a counterclockwise direction as the lever 168 upon which it is mounted is prevented from moving in a similar direction by the shoulder engaging the fiat sided pin 166. Near the end of the rst cycle of the shaft 74 a cam 172 pinned to the shaft Will engage a roller 17 3 carried on the right hand end of iis icc

a lever 174 and cause said lever to rock on its pivot 1123 and swing the arm 164i clockwise on its pivot to disengag'e the shoulder 165 from the flatsided pin 166, as shown in Fig. 10. The left hand end of the lever 174tis formed on an angle where it engages a roller 175 carried on the. lower end of the arm 1611-.

lVith the flat sided pin 166 disengaged from the shoulder .165 a spring' 176 will move the lever 168 and arm 119.2 counter-clockwise until the projection 124e on the arm 122 ens the roller 125 carried on the lever 126, where it will be arrested until the cam 171 engages the bell crank arm 170 during its second. cycle of operation, when the lever 166 and its associate parts will be returned to their home position by the cani 171, and the shaft 74, will be stopped after its second cycle as in the iirst embodiment. A springI 177 attached to the lever 126 is of ,ejreater strength than the spring' 176 attached to the arm 16T which will prevent the lever moving counter-clocki'ise until moved by the cam 171. lilith the arm 122 in its hmne position the shaft 56 will continue its rotation to return the item key and its associate'parts to their home position as in the first embodiment.
